JBOSS_HOME 未在 Eclipse Linux、System.getenv 中正确设置 returns null

Question

我在 Linux 和 Windows 中添加了 JBOSS_HOME。

这是我的 arquillian.xml

http://jboss.org/schema/arquillian/arquillian_1_0.xsd">

    <container qualifier="NON_REST_CONTAINER">
        <protocol type="Servlet 3.0">
        </protocol>
        <configuration>
            <property name="allowConnectingToRunningServer">true</property>
        </configuration>

    </container>

     <container qualifier="REST_CONTAINER"  default="true">
        <protocol type="Servlet 3.0">
        </protocol>
        <configuration>
            <property name="allowConnectingToRunningServer">true</property>
        </configuration>
    </container> 
</group>

在 windows 中测试运行正常，但在 Linux 中我遇到以下异常：NullPointerException 由于 jbossHome 变量在 ManagedDeployableContainer[=18 中为空=]

        final String jbossHome = config.getJbossHome();
        File jbossHomeDir = new File(jbossHome).getCanonicalFile();

这是异常跟踪：

特别是由于：

所以，我的解释是 JBOSS_HOME 没有被 Arquillian 正确读取，不知道为什么。

当我在 arquillian.xml 中添加 jbossHome 属性时，它在 Linux 中也能正常工作。但我不想这样做，因为 Linux 和 Windows 的路径会有所不同，我希望它兼容。

任何 suggestions/pointers 将不胜感激。

更新：

我尝试从独立程序 System.getenv("JBOSS_HOME") 并从终端运行打印 JBOSS_HOME ，但从我的 eclipse/testcase 来看，它 returns 为空。

Answer 1

在 Eclipse 中，您可以在 JUnit 测试启动器的 Environment 选项卡中设置 JBOSS_HOME 环境变量。这是一种解决方法，以防未在系统级别（不是 shell 级别）定义环境变量。

在 Eclipse 中，

使用主工具栏中的 "Run configuration..." 菜单打开启动器配置对话框（使用运行图标右侧的箭头）。
然后 select 你想要的 JUnit 测试运行，select Environment 选项卡并点击 New 添加 JBOSS_HOME 环境变量到测试你会运行.

Answer 2

在 /etc/environment 文件中定义键值对。现在注销并登录以应用更改。它将使这些变量可用于所有进程。

JBOSS_HOME=<JOBSS-PATH>

因此，您不必从终端运行 eclipse shell 来使环境变量可见。

对我有用。

JBOSS_HOME 未在 Eclipse Linux、System.getenv 中正确设置 returns null

JBOSS_HOME is not properly being set in Linux, System.getenv from Eclipse returns null
